Hello @anujdeshpande I refered your documentation steps as in https://www.hackster.io/anujdeshpande/state-of-the-city-b81d85, it is really great work to track sensor events in map for some environment monitoring demo app. However it is not working and I'm getting authentication error from s3 bucket as "<Error>

<Code>AccessDenied</Code>

<Message>Access Denied</Message>
